We need to talk about naked mole rats - The Oatmeal

This is a comic about naked mole rats, aka tube goblins.

The Oatmeal

Yes, you may be killed by falling human made space junk, but the odds remain small(ish) that will occur. The (almost inevitable) #KesslerSyndrome may also prevent future #space flights if all those #satellites in Low Earth Orbit start colliding, creating countless debris.

However, we *ALL* have to worry about the ‘chemical problem’ being created by SpaceX et al in the upper atmosphere. I have been banging on about this for a while and the attached article summarises the science in an easy to understand way - I have pasted the bit about the ‘chemical problem’ below because we *ALL* need to understand what the billionaires are doing to the planet while we are watching.

Debris on the ground attracts immediate attention, but atmospheric scientists are tracking a slower process with potentially larger consequences. When satellites vaporize in the mesosphere, 50 to 80 kilometers above Earth, they release clouds of vaporized metals that condense into aerosol particles. Those particles descend into the stratosphere, where Earth’s protective ozone layer resides.

Aluminum is the element of greatest concern. Upon reentry, aluminum oxidizes into aluminum oxide nanoparticles. A single 250 kilogram satellite generates roughly 30 kilograms of these particles. Unlike chlorofluorocarbons, which directly destroy ozone, aluminum oxide acts as a catalyst. One particle can facilitate chemical reactions that destroy thousands of ozone molecules over decades without being consumed.

Researchers from the University of Southern California’s Department of Astronautical Engineering documented an eightfold increase in atmospheric aluminum oxides between 2016 and 2022, directly correlating with the proliferation of satellite constellations, a finding reported in detail by CNET. In 2022 alone, reentering satellites released an estimated 41.7 metric tons of aluminum, approximately 30 percent more than the natural input from micrometeoroids.

Projections based on current deployment schedules suggest annual aluminum oxide emissions could reach 360 metric tons, a 646 percent increase over natural background levels, according to research highlighted by Popular Mechanics. Because these particles take 20 to 30 years to descend into the ozone layer, the atmospheric chemistry of today’s satellite fleet will not manifest as measurable ozone loss until the 2040s. By then, the upper atmosphere could already be saturated with catalysts.

NASA high altitude sampling flights over Alaska in 2023 detected the signature of this process. At approximately 60,000 feet, instruments found that 10 percent of stratospheric sulfuric acid particles larger than 120 nanometers contained aluminum and other metals traceable to spacecraft reentries, according to data presented at the American Astronomical Society meeting that year. The atmosphere now bears a permanent chemical marker of human activity in space.

Starlink Is Dropping From the Sky Again and Again. Scientists Warn Earth Is Already Feeling the Effects

For decades, space safety rules assumed satellite reentries would stay rare. By early 2026, with over 70,000 megaconstellation spacecraft planned, that assumption has collapsed.

Since #ZFS snapshots came up as a #sysadmin helper I figured I'd share something that has saved my butt many, many times in #FreeBSD over the years.

If you're going to in-place update a long running service, even when you do a before-and-after zfs snapshot, ALWAYS make sure the service restarts fine before you touch anything. ALWAYS.

There are not many things worse than doing a snapshot, update, spending hours trying to get a service to start and rolling back bit by bit before finally giving up and restoring the snapshot - only to discover that the service had silently broken weeks ago and wouldn't have started cleanly at all no matter what. Only update a verified-working system.

Its right up there next to some of my other personal golden rules:
* if you're going to remotely administer a machine, do the install remotely even if its temporarily on your desk. Find out on day 1 if a reinstall will be a problem.
* When you touch a 24x7 system, always make sure it comes up cleanly after a reboot or power cycle with hands off. If you had to fix something during the boot, then test it again. Repeat until it comes up cleanly, hands-off.

I know - containers, cloud, CI/CD, etc, etc. Let me have my moment!
At some point I need to write a long post about all of the UI mistakes that Signal makes, because I keep reading posts about how the Signal UI is great and it makes me sad how badly WhatsApp and friends have broken everyone's expectations.
Da Hausdurchsuchungen ja immer öfter als eine alternative Strafe eingesetzt werden, insbesondere in Fällen, in denen Schaden durch die Maßnahme in keinem Verhältnis zu Tat/Urteil stehen, würde ich vorschlagen, das wir solche Maßnahmen ähnlich unbürokratisch entschädigen.

There’s an old and quite simple investment scam that works something like this:

You set up a dozen or so funds. Each fund invests in a random set of stocks. On average, they will perform about as well as the market, but there will be a distribution. Some will lose money, some will make money.

You take the ones that significantly outperformed the market and advertise them as the result of your genius secret investment strategy. You get a load of people to invest. And then you have their money to invest in whatever yo want (such as your own businesses, or things you own and can sell and make a big profit from).

I feel like a lot of big companies have the same attitude towards promotions to senior leadership. They take a load of people who have made predictions and promote the ones that made correct ones, but never look at why they made the decisions. A process like this needs to do a proper analysis of the reasons for the choices.

This kind of analysis often happens for incorrect choices. When a project fails that management thought would succeed, some places do an analysis of why it didn’t go as expected. But when a project succeeds, no one looks to see whether it was because of luck or judgement. And when you promote people because they were lucky and tell them that it was because of skill, you end up with people who make more and bigger gambles, right up until they make one that is a disaster.

Wir veröffentlichen die Dokumente zur Fördermittelaffäre der Berliner CDU!
Mit dem Informationsfreiheitsgesetz haben wir Protokolle, Vermerke und Mails befreit, die zeigen: Die CDU vergab Millionen Euro an Projekte zur Antisemitismusbekämpfung ohne Qualitätskriterien, ignorierte Bedenken der Verwaltung und setzte einfach eigene Parteiinteressen durch.

Mehr zum Thema gibt's auch bei der SZ – alle Dokumente und eine Chronologie der Fördermittelaffäre gibt's hier: https://fragdenstaat.de/artikel/exklusiv/2026/01/die-akten-zur-berliner-fordergeldaffare/

CDU-Fraktion: Die Akten zur Berliner Fördergeldaffäre

Berlin stellt Millionen Euro für Projekte gegen Antisemitismus bereit. Doch die Berliner CDU setzte scheinbar die Kulturverwaltung unter Druck, nach ihren parteipolitischen Wünschen zu entscheiden. Wir veröffentlichen die Akten.

I feel like a lot of the hate Liquid Glass gets should be directed to the previous versions of iOS that have set my expectations so low for Apple’s mobile UIs that my reaction to Liquid Glass was ‘meh, it’s probably not in the top ten worst things they did on iOS’.
